Make your steam system safe,
efficient and sustainable
The duty of a steam trap is to discharge condensate
while retaining live steam in the system. This ensures
your steam system is able to operate efficiently, without
the detrimental effects of unwanted condensate essential in temperature critical applications.
Condensate in the system can lead to a number of
issues such as:
- Poor heat transfer
- Damage to system and process equipment
- Poor quality or wasted product
Selecting the right steam trapping solution helps to
avoid these problems, whilst at the same time allowing
the condensate to be recovered. Information on the
significant benefits of recovering condensate can be
found at the back of this brochure.

An introduction to steam traps
Each steam application has its own steam trap requirements. Selecting the right steam trap for your application could have
a significant, positive impact on your process, potentially improving efficiency, reducing energy costs and giving you a safer
working environment.
For example: condensate must be removed promptly from a plant where maximum heat transfer is sought at all times. The
presence of excess condensate in an item of heat transfer equipment will reduce its efficiency, preventing it from achieving its
maximum rated output and may also reduce its service life.
However; in other applications, it may be required to hold back the condensate to extract some of its heat and thus save
on steam. Furthermore, by discharging condensate well below steam temperature, flash steam losses can be reduced or
avoided altogether.
Thermodynamic steam traps
Maintaining optimum process performance
Thermodynamic steam traps are the best choice for steam mains drainage due to
their simplicity, long life and robust construction. With a large condensate capacity for their
size, the all stainless steel construction of our thermodynamic traps offer a high degree of
resistance to corrosive condensate.
Mechanical steam traps
Maintaining optimum process performance
Mechanical steam traps are ideal for use on process applications where condensate
must be removed as soon as it forms, to safeguard against temperature fluctuation
which would lead to issues such as product spoilage and inadequate heating. Our
mechanical steam trap range is adaptable to all applications where instantaneous
removal of condensate is required.
Thermostatic steam traps
Utilising heat energy in condensate
For applications where it would be desirable to make use of the heat in the condensate
such as sterilisation, a thermostatic steam trap is an ideal solution as it will not open
until the condensate temperature drops below saturated steam temperature. This
allows the heat in the condensate to be utilised before it is drained off which in turn
reduces flash steam losses and can help to reduce energy costs.
Spirax Sarco offers a complete range of steam traps to ensure you can
select the perfect trap for your application.

How a thermodynamic steam trap works

1. On start-up, incoming pressure raises the disc and cooled
condensate, and air is immediately discharged.
2. Hot condensate flowing through the trap releases flash
steam. High velocity creates a low pressure area under the
disc and draws it towards the seat.
3. At the same time there is a pressure build-up of flash steam
in the chamber above the disc which forces it down against
the pressure of the incoming condensate until it seats on the
inner ring and closes the inlet. The disc also seats on the
outer ring and traps pressure in the chamber.
4. Pressure in the chamber is decreased by condensation of
the flash steam and the disc is raised. The cycle is then repeated.
Features and benefits:
• Positive condensate discharge with clean tight shut-off
• Discharges condensate at very close to steam temperature
that ensures maximum plant efficiency
• Just one moving part, a disc, ensures reliable operation
and minimal maintenance without having to remove from the line
• Compact and light weight, reducing installation costs
• Hardened disc and seat for long life
• One trap covers a wide range of operating pressures making
selection and replacement simple
• Insulating cover for low ambient temperature or wet environments
• Thermodynamic traps can be used on high pressure and superheated steam
and are not affected by waterhammer or vibration.

Mechanical steam traps
Ball float mechanical steam traps
Ball float (FT) mechanical steam traps have an integral air vent as standard and the options of a manually adjustable
needle valve (SLR - steam lock release mechanism) and drain cock tapping, the FT range is adaptable to all applications
where ball float traps are recommended and instantaneous removal of condensate is required.
How a ball float steam trap works
1. On start-up a thermostatic air vent allows air to bypass
the main valve (1) which would otherwise be unable to
escape (a condition known as ‘air-binding’).
1
2
3
4
2. As soon as condensate reaches the trap, the float is
raised and the lever mechanism opens the main valve.
Hot condensate closes the air vent but continues to flow
through the main valve.
3. When steam arrives the float drops and closes off the
main valve, which remains at all times below the water
level, ensuring that live steam cannot be passed.
4. As the steam condenses, the float rises allowing
condensate to be released.
Features and benefits:
• Immediate condensate discharge with clean, tight shut-off. No backup
of condensate ensures maximum plant efficiency
• Works efficiently on both heavy and light loads with no passage of
live steam
• Not affected by wide and sudden fluctuations of pressure
or flowrate
• Stainless steel internals that can tolerate corrosive
condensate
• Integral air vent to ensure rapid warm-up of plant
• Robust construction to guarantee long life against
waterhammer and vibration.

Mechanical steam traps
Inverted bucket mechanical steam traps
Our inverted bucket steam traps employ a well-proven principle which relies on the difference in density between steam (a
vapour) and condensate (a liquid). They have a robust design and incorporate a simple density sensitive bucket and lever
mechanism.
How an inverted bucket steam trap works
1
2
3
4
1. As condensate reaches the trap it forms a waterseal
inside the body. The weight of the bucket keeps the valve
off its seat. Condensate can then flow around the bottom
of the bucket and out of the trap.
2. When steam enters the underside of the bucket it gives
it buoyancy and the bucket rises. This positions the lever
mechanism such that the main valve ‘snaps’ shut due to
flow forces.
3. The bucket will lose its buoyancy as the enclosed
steam condenses due to radiation losses and steam
escapes through the vent hole. Once this happens the
weight of the bucket will pull the valve off its seat and the
cycle is then repeated.
4. Any air reaching the trap will also give the bucket buoyancy and close the valve preventing condensate flow. The
small vent hole positioned at the top of the bucket will lead air into the top of the trap. Because the vent hole at the top of
the bucket is small in diameter it will vent air very slowly. Where the venting of air may be a particular problem, this can
be overcome simply by fitting an external air vent in parallel.
Features and benefits:
• Near continuous condensate discharge with tight shut-off. Minimal
back-up of condensate ensures maximum plant efficiency
• Deep water-seal to protect against the possibility of steam loss
• Suitable for superheat conditions when fitted with internal inlet check valve
• Simple and robust construction to guarantee long life against
waterhammer and vibration
• Stainless steel internals are attached to the cover for ease of maintenance
• Integral strainer (HM, HM34 and SCA models only)
• Optional blowdown valve (only for HM and HM34).

Thermostatic steam traps
1
How a balanced pressure thermostatic steam trap works
1. On start-up, cold air and condensate enter the trap. As the capsule is also cold, the valve
is open and the air and condensate are discharged.
2. The capsule warms up as the condensate approaches steam temperature. Its liquid
filling boils, and the resultant vapour pressure acting on the diaphragm pushes the valve
head towards the seat, fully closing at the selected discharge
temperature before any steam is lost.
2
3. As the condensate within the trap cools, the vapour filling
condenses and the internal capsule pressure falls. The valve
reopens, discharges condensate and the cycle repeats.
Features and benefits:
• Condensate is discharged at below steam saturation temperature, utilising sensible heat in the
condensate and reducing flash steam losses
• Automatically discharges air and other incondensable gases to aid rapid warm-up of plant
• It automatically adjusts itself to variations of steam pressure up to its maximum
operating pressure and can tolerate superheat up to 70°C
• Discharge temperature set by capsule selection – no requirement to adjust on site
• Manufactured using advanced technology
to exacting quality standards
• All stainless steel internals extend working life
and reduce plant maintenance
• The BPC32 and BPS32 series has a two bolt
cover design for ease of maintenance.

Thermostatic steam traps

How a bimetallic thermostatic steam trap works
1. On start-up, the bimetallic element is relaxed and the valve is open. Cooled condensate,
plus air, is immediately discharged.
2. Hot condensate flowing through the trap heats the bimetallic element causing it to pull
the valve towards the seat.
3. As the hot condensate is discharged and approaches steam
saturation temperature the bimetallic element closes the valve.
When there is no flow through the trap the condensate
surrounding the element cools causing it to relax and the
upstream pressure opens the valve. Condensate is discharged
and the cycle repeats.
Features and benefits:
• Condensate is discharged at below steam saturation temperature,
utilising sensible heat in the condensate and reducing flash steam losses
• Automatically discharges air and other incondensable gases to aid
rapid warm-up of plant
• The bimetal elements can work over a wide range of steam pressures
without any need for on-site adjustment
• Resistant to waterhammer and freezing
• The SMC32 series has a two bolt cover design for ease.

The benefits of effective steam trapping
Spirax Sarco are focused on helping our customers achieve process efficiency, increased production output and
energy savings, and we know the importance of effective steam trap management in achieving this. A healthy
steam trap population allows condensate to be removed from the steam system effectively which means it can be
re-used. We call this ‘condensate recovery’ and it saves energy and cost in a number of different ways:
Reduced fuel costs
Normally, condensate will contain around 25% of the usable energy of the steam from which it came. Returning
this to the boiler feedtank can save thousands of pounds per year in energy alone.
Energy saving
Condensate returned to the feedtank reduces the need for boiler blowdown, which is used to reduce the
concentration of dissolved solids in the boiler. This therefore reduces the energy lost from the boiler during the
blowdown process.
Reduced water charges
Returning and re-using condensate reduces the requirement for fresh replacement water.
Reduced chemical treatment costs
Re-using as much condensate as possible minimises the need for costly chemicals to treat raw water.
Reduced effluent costs
In many countries there are restrictions on releasing effluent at elevated temperatures so it must be cooled if
discharged which incurs extra costs.
Spirax Sarco are always on hand to advise you about the best ways to manage your steam system and to help
ensure you continue to reap these benefits.
